Re: "But activists on the left also acknowledge that their side has changed, too."

They have changed (a little bit) and need to change a whole lot more. If they can emphasize the corruption of having the richest people in the world feeding from the government trough while the poorest among us lose their benefits, that's a winner. If they can talk about how wrong it is to have the military -- which is supposed to be outwardly facing -- acting like police, that's a winner. If they can keep some focus on the sheer stupidity, incompetence and malice of the people Trump has put in charge of everything, that's a winner.

If they keep trying to talk about how great having trans people playing women's sports, well, they'll get what they've gotten and we're all screwed.
